lle it known that we, Janes li. W. licii- .urosand Cniinacs llplliciiaiuis. citizens ot' the tfnited States. residing at Arapahoe, in the county ot l `nrn:.s, State of Nebraska` have invented a new and useful Funnel, oi which the `following is a speeil'ication.

lt'is` the object ot the presentI invention to provide an iniprored construction of funnel and more .--pccilically to provide a' funnel having a vent so arranged and constructed as to obviaie interference of the liquid, pass- I ing through the i'unnel` with thi. air escaping troni the being poured: Ordinarily such tunnels are constructed with their vent tubes or siniilai devices terminating at the lowci' end of their necks, but such a construction is undesirable inasmuch i and as a inattcr ot t'act'l does iutcr'lere with the passage ot' the liquidV through the neck and into the vessel poured.

lii the accompanying drawings, Figure t is a vertical sectional viewl through a it'unnel `coiistriieiwl i-n accordance with the present invention. the seclioii being taken in a plane passing through thc vent ofthe funnel. Fig. j is a'view similar to Fig. 'l but taken in a plane at right angles to the plane of Fig. l and showing the air vent tube in eleyatioii. and ltig. :l is a horizontal sectional' 'view through the neck of the funnel.

.\s heretofore stated. and as will be obviews ot' the drawings, the exterior surface is plane oi' in other words unbrokenl` so that the neck ot' the funnel, owing to its shape, adapted to be titled snugly into the. neck of a bottle oirol her vesseli into which liquid is in nearly all ventioii are 'other than those which ordinarily accrue from such construction.

tube for the escape of air from the vessel into which the liquid is being` poured, and thisl tube is formed by securing. by soldering or otherwise, to the inner surface of the body 5 and neck t3 orf the :t'uniiel, a strip of sheet metal or other material of which the Ifunnel itself may be made, which strip is indicated by the numeral T and is convened trans- I versely throughout its length as is clearly shown in all of the figures of the drawing, it being soldered at its edges to the interior surface ot' the body 5 and also to the interior surface ol' the neck G althourh it is preferable that flanges 8 be proif'idjed along those edges of the strip which are secured to the of the neck, these iianges being soldered or secured in any other suitable manner to tliesaid surface of the neck. lt will be observed iroin an inspection of the drawings and principally Fig. 3 thereof that the strip, owing to its transverse curvature.A toi-nis, in conjunction with the said .sur-tace ot' the body 5 and neck a tube or vent tube as it will be termed in the. claiin.

lt is prcibrable in constructing the funnel embodying the present invention, that the upper end of the vent tube just described; be closed and to this end` the strip comprising the tube iii iart, is Jrovided or has secured 7 thereto at the said upper end a small sheet or [lange of the material of which the tube l also to the inner surface of the body 5 of .l'n the drawings. the body of the tuniiel'is i (i'eady exit, the tube at its said upper end and immediately below the strip or flange torined or secured thereto, is provided with a slot Vl0 which extends transversely thereoi l and through which the air may escape. At. served 'troin an inspection oli the seveial its lower end, the strip 7; projects downiwai'dly below the lower end ot the neck (3 of both the. body and tlie neck of the. funnel ot' thejtunnel to an appreciable degree, still retaining its convexity and it is this projection of the strip below the lower end ot' the neck ot the funnel that prevents inter- `ference ot the l struetcd -with the lower end of the vent teri l iiiinating at the lower end of the neck of the funnel.

From the foregoing description of the invention, it will be understood that any liquid introduced into the funnel will tiow through the neel( 6 thereofl into the reeeptaele. into which the said neck is inserted and that the will escape therefrom by way of the air vent tube heretofore described, and it will he further understood that the downwardly projecting lower end portion of this tube or rather the strip forming a )ortion there of, eectually prevents` inter erence ot' the outrpshing air with the iniowing liquid, and that consequently the liquid will iiow more freelgvv through the funnel than would be the case were the vent terminated in av plane with the lower` end of the neck of the funnel. Itwill further he understood that inasmuch aS, the neck of the funnel is frusto-conicalfin form and has its outer surface practically."unbroken, it' may be fitted or other suitablgyessel to be filled and that also inasmuch as the air vent tube is located of the funnel and is provided with the downwardly projecting which is indicated in the drawings by the numeral 11, should the bottle or other vessel become filled to overflow i ing` some o1' the liquid contained therein A funnel ha vini.;` a` Si rip secured upon the inner surface tl'ufreo'l and extending downwardly and below the lower end of the neck thereof and cooperating with the Said inner i surtaee of the wall ot the funnel t'o atl'ord l a rent, the upper end of the vent tube thru; formed being closed and the strip being slotted substantially throughout. its width,

the lower end of the Istrip beingeouvexed and extended below the lower end ot' the neck of the funnel with its concave or open side presented away from the-axis" of the funnel.

In testimony that we claim the foregoingA as our own. we have hereto aflixed our sig natures in the presence of two witnesses.
